A review of copper cyanide recovery technologies for the ...

2012-1-1 · The most widely adopted method for the treatment of cyanidation tails is the Inco SO 2 /air process (Robbins, 1996). This process involves the use of SO 2 (or other sulfite source), which reacts together with oxygen and copper cyanide complexes, resulting in cyanide oxidation to cyanate. At the end of the reaction, copper is precipitated out as ...
